With some substrates, may have no effect on coalescence. Consider trying a new roll. Some substrates deteriorate during long periods of storage. Remove Increase Decrease Slower printing Less durability (smudges), oily finish If necessary, load a self-adhesive vinyl to achieve good alignment Decrease Reduced color gamut Increase Reduced gloss in dark area fills. With some substrates, may have no effect on bleeding or wicking. ENWW 171
